Product Description

Specifications

Principle of single acting actuator (spring return)

Counter-clockwise

Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A.

Clockwise

Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A.

Principle of double acting actuator

Counter-clockwise

Air to port B forces the pistons outwards,causing the springs to compress, The pinion turns counterclockwise

Principle of Double Acting Actuator

CCW

Air to Port A forces the pistons outwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port B.

Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A.
